+====== What model runs might be relevant ======
+There are a lot of different model runs available as part of PMIP. In fact the amount of output can be a bit overwhelming at first. On important distinction is the different between *transient* and *equilibrium* simulations. All climate models are run forwards in time and write output every month/day. So this distinction really relates to the forcing inputs, and the climate response to them. From a practical perspective, you should be looking at the long-term statistics of the equilibrium simulations, and the temporal variations in the transient simulations. There are more details and links below, but a quick division of the experiments is...
+  * **PMIP4/CMIP6 Equilibrium Simulations**
+    * **piControl** (Preindustrial): //The control run that all the climate changes can be calculated from//
+    *  **abrupt4xCO2** (Instantaneous quadrupling of carbon dioxide): //An idealized global warming experiment (primarily included for calculating the climate sensitivity)//
+    * **midHolocene** (6,000 yrs ago):  //Useful for identifying impacts of orbital forcing//
+    * **lgm** (The last glacial maximum at 21,000 yrs ago): //The archetypal cold climate state//
+    * **lig127k** (Last Interglacial, 127,000 yrs ago): //Peak of the warm period prior to last glaciation//
+    * **Eoi400** (Pliocene, 3,205,000 years ago): //warm conditions before any Northern Hemisphere glaciation (minimal continental drift)//
+    * **DeepMIP** (Eocene & Paleocene, 50-60 million yrs ago): //Warm climates with carbon dioxide concentrations similar to end of century projections (continents drifted, PMIP-only)//
+  * **PMIP4/CMIP6 Transient Simulations**
+    * **1pctCO2** (Carbon dioxide concentrations increase by 1% per year): //An idealized global warming experiment (primarily included for calculating the transient climate response)//
+    * **historical** (1850CE onwards): //Free-running simulations of industrial era (so climate variability's phase/sign does not match observations, but its statistics should)//
+    * **past1000** (last millennium, 850CE onwards): //Free-running simulations seeing 1000+ years of climate forcings//
+    * **LDv1** (last deglaciation, 21,000 years ago to present): //Very-long simulation that encompasses all forcings (PMIP-only)//
+  * **Other Transient Simulations** //There are several other long palaeoclimate simulations that my be useful//
+    * **[[https://www.earthsystemgrid.org/project/trace.html|TraCE]]** This simulation runs from 22,000 years before present (22ka) to 1990 CE as well as single-forcing sensitivity simulations of varying lengths. Contact [[mailto:ottobli@ucar.edu|Bette Otto-Bliesner]]
+    * **[[https://www.clim-past-discuss.net/cp-2018-140/|MPI]]** Simulations with both fast and slow forcings from 8000ka-present. Contact [[mailto:johann.jungclaus@mpimet.mpg.de|Johann Jungclaus]].
+    * **[[https://doi.org/10.1029/2018GL079337|Kiel]]** Simulations of both the Holocene and the Eemian exist for the Kiel model. Contact [[mailto:vyacheslav.khon@ifg.uni-kiel.de|Vyacheslav Khon]].
+    * **[[https://www.palmod.de/home|AWI]]** Slowly a simulation from the Last Glacial to present is being is created. Contact [[mailto:Gerrit.Lohmann@awi.de|Gerrit Lohmann]]
+    * **[[https://www.clim-past-discuss.net/cp-2018-140/|IPSL]]** Several simulations from 6000ka to present have recently been performed in France. Contact [[mailto:pascale.braconnot@lsce.ipsl.fr|Pascale Braconnot]] and Olivier Marti.
+    * **[[https://link.springer.com/article/10.1007/s00382-011-1283-y|FAMOUS]]** A simulation of the last glacial cycle with accelerated-forcing. Contact [[mailto:r.s.smith@reading.ac.uk|Robin Smith]]
+    * **[[https://www.paleo.bristol.ac.uk/ummodel/scripts/papers/Singarayer_and_Valdes_2010.html|HadCM3]]** There are a series of equilibrium simulations of HadCM3 run over the last glacial cycle. A version of these does exist with water isotopes. Contact [[mailto:j.s.singarayer@reading.ac.uk|Joy Singarayer]]
